When you need to track temperature and humidity in a lab, storage area, or field setting, a data acquisition recorder is the everyday tool that captures readings for later review. The decision often comes down to two things: what the logger costs and what is included out of the box. These two recorders show that trade-off clearly-one is a new Dickson DWE with a lower listed price, but the sensor is not part of the package; the other is a used Vaisala RFL100 with a higher listed price and a compact portable design.
Quick verdict
If you want the lower listed price and are ready to supply your own sensor, the Dickson DWE Data Logger is the DicksonOne option at USD 119.99. It is listed as new, and the box includes the logger only. If you prefer a complete portable package with an HMP110 temperature and humidity sensor and you are comfortable with a used unit, the Vaisala RFL100 at USD 239.00 is the more inclusive pick. Neither option is a universal winner; the right choice depends on whether you prioritize upfront cost or an all-in-one package.
Comparison at a glance
| Product | Listed Price | Price Bar | Key Details |
|---|---|---|---|
| Dickson DWE Data Logger Temperature & Humidity DicksonOne - NEW | USD 119.99 | New; sensor not included; MPN DWE | |
| Vaisala RFL100 Data Logger w/ HMP110 Temperature and Humidity Sensor | USD 239.00 | Used; compact portable design; includes HMP110 temperature and humidity sensor; Model RFL100 |
Where each product wins
Dickson DWE: The listed price is lower, the unit is listed as new, and the DicksonOne model is identified by MPN DWE. If you have a sensor available or plan to source one separately, the DWE gives you a new logger body without paying for a sensor you may already own.
Vaisala RFL100: This package pairs the RFL100 with the HMP110 temperature and humidity sensor, creating an all-in-one setup. The description highlights a compact and portable design, which is a practical advantage when you need to move the recorder between locations. The trade-off is that the unit is listed as used.
Product notes
Dickson DWE Data Logger Temperature & Humidity DicksonOne - NEW
The Dickson DWE is the new logger in this comparison, listed at the lower end of the price pair. Its price position is the headline: it gives you a DicksonOne unit with model number DWE, and the description indicates it comes in its original box. That makes it a sensible choice if you already have the temperature/humidity sensor you need or plan to buy one separately. The most important limitation is spelled out in the description: the sensor is not included. You are getting the logger body and not the sensing element, so the total cost may go up once you add a compatible sensor. Also, the gtin value is "Does not apply"-helpful to know only if you use GTINs for inventory. If you want a lower sticker price and are willing to assemble the sensing half yourself, the DWE is the candidate.
Vaisala RFL100 Data Logger w/ HMP110 Temperature and Humidity Sensor
The Vaisala RFL100 sits at the higher price point in this comparison, but it arrives as an all-in-one package: the logger body is paired with the HMP110 temperature and humidity sensor named in the title. That removes the need to track down a separate sensor. The description also highlights a compact and portable design, which is helpful if you need to move the recorder between monitoring spots or fit it into a small space. Because this unit is listed as used, you are inheriting a secondhand device rather than a brand-new one. If you prefer new gear and have a sensor available, the DWE may be more appealing; if you want a portable logger with the sensor already included, the RFL100 is the one to choose. The Finland origin and RFL100 model identify the unit, but the practical draw is the included sensor and portability.
Final choice by use case
- When you want to minimize upfront cost: The Dickson DWE is the new logger with the lower listed price, and it is the right starting point if you can add the sensor yourself.
- When you want an all-in-one portable package: The Vaisala RFL100 includes the HMP110 temperature and humidity sensor and is described as compact and portable, making it the better fit for moving between locations.
For a straightforward decision, choose the Dickson DWE for the lower listed price on a new logger body, or choose the Vaisala RFL100 for a used, portable setup with the sensor already included.
